INVENTOR. EDWARD AL BEAI' MAUBVBEFG I I This invention app Patented July1, 1936 V, EDWARD A. TANGENBERG, or GRAND RAPIDS, MICHIGAN V HINGEApplication filed April'ze,

ertains tohinges and more particularly to hingesof thetype em bodying'a' support associated therewith, so

that the'hingewill act as means for limiting.

the swinging movement of the leaves of the hinge relative toone anotherand for sup porting a device to which one of the leaves is connected. v"one of the primary objects of this invention is to provide a novel deskhinge, which isso constructedas to fully support a lid of a desk in afully open position flush with the 'bedof the desk so as to permit saidlid tobe used as a writing surface,'the leaf of the, hinge beingcountersunk in the edge of the lid so-as to-permittheentire top surfaceto be used as a writing portion.

Another important object ofmy invention is the provision of a hingehaving a toggle, forming a support, hingedly connected to the leavesofthe hinge, the toggle being so arranged as to rest on the hinge itselfwhen i the lid of the desk is open in horizontal position flush with thebed of the desk, the bearing surface of the toggle seating on the edge 1of the toggle and not at the ends thereof.

A further. object of my invention is the provision of a combinationsupport and hinge embodying a pair of fiat leaves arranged at rightangles to one another pivotally connected together at their inner endsby means of a rivet or pivot pin, with a toggle connected to the leaveson each side of the pivot point thereof through the medium of suitablepivot ears formeddirectly on said leaves.

A still further object of my invention is to provide an improvedcombination hinge and support of the above character, which will bedurable and eflicient in use, one that will be simple and easy tomanufacture, and one which can be placed upon the market at a reasonablecost.

With these and other objects in view,'the invention consists in thenovel construction, arrangement and formation of parts, as will behereinafter more specifically described, claimed, and illustrated in theaccompanying drawing, in which drawing: I

Referring to the drawing in detail, wherein similar reference charactersdesig nate corresponding parts throughout the several views, the letterA generally indic'ates my improved hinge and B a desk with whichthe'sameca'n be associated; I have only shown a fragment of the deskBand the same includes the swinging lid 10 and be connected-' by meansof my novel hinge.

I My hinge A comprises leaves 15 and 16 which are preferably formedfroinflat sheet metal and the leaf 15 is preferably dis leaf l6 isdisposed-onedge in a vertical plane, tothe top fa'ce'of thebedll, as clearly shown,and the leaf 16 secured to the edgeofthe lid 10, as shown. 'These leavesare preferably coun tersunk respectively in-the top face of'the bed andin thesideedgeof the lid, suitable screws 17 being employed for holdingthe leaves in place. The-forward end of the leaf l5 hasfformedo'nits'side edge a depending so" posedfiatin: a horizontal planewhile'th'ej' ear 18 whichcan be likewise countersunk'in the side edge ofthe bed 11 if preferred;

This ear projects slightly beyond the for-f Ward edge of the leaf 15 andis arranged in overlapping relation with the pivot: ear 19 formed on theinner end of'the leaf l6; The A ears 18 and 19 are connected together'byarivet or pivot pin 20 which permits the free swinging of the leavesrelative to one anare Each leaf has ,formed thereon intermediatetheendsthereof upstanding pivot ears 21 and'j22c respectively and it canbe 5 seen 'that' the pivot ears: 21 is turned at right angles "to-{thebody portionof the leaf,
